[TowerTalk] Bobtail Curtain

Works well for me on 30M.  Did the initial work on the parallel resonant 
circuit on the workbench by putting a 7K resistor across the coil and using 
my MFJ analyzer to find the 50 ohm tap point for the feedline.  Had to make 
minor readjustment of the tank circuit to achieve resonance after attaching 
the center leg of the antenna (used dip meter).  I made the verticals and 
horizontal a bit longer than the optimum (after modeling with EZNEC) to get 
a bit of side lobe. Used RG-213 section as the capacitor in the tank 
circuit.
